will the potential difference across 2ohm resistors be same as that across the parallel combination of 4ohm resistors.Give reason, I need proper explanation in few words
Answers
In parallel combination of resistors around a circuit, the potential difference between the points having the resistors arranged parallely, is equal or same. Because they are between same points
☃️ Refer to the attachment....
When resistors are connected in parallel combination:
- The potential difference between in each resistor is equal to the applied potential difference/Voltage.
- But, current divides because the stream divides. The sum total of current flowing through each resistor is equal to total current in the circuit.
- The net resistance or equivalent resistance is smaller than each of the resistance.

Resistors are combined in either series or parallel combination. When they are attached end to end, it is series combination and when they are attached parallel to ach other, it is parallel combination.
⚡We already knew about parallel combination, Here is something about series combination:
- The potential difference is not same for all. The sum total of potential difference is equal to applied voltage.
- As their is no division in stream of current, same current flows throughout the circuit.
- The equivalent resistance is more than each of the resistor combined.
⏏ Series combination is used in decorative lights for festivals in which we can switch on the lights once at a time. Parallel combination is used in our home regular circuits, so that if there is any break, the other appliances keep working.
